  • Value of Joint Fluid and Blood-related Indicators in the Diagnosis of Gouty Arthritis and Rheumatoid Arthritis

    ObjectiveTo discuss the changes of joint fluid and blood-related indexes in patients with gouty arthritis and rheumatoid arthritis, and to analyze the clinical significance of these changes. MethodsSeventy-five patients with gouty arthritis and 68 with rheumatoid arthritis treated between January and December 2014 were included in our study. Their joint fluid-related indicators including white blood cell count (WBC), total protein (TP), albumin (ALB), glucose (GLU), and uric acid (UA), and their blood indicators including immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA), C3 and C4, rheumatoid factor (RF), anti-streptolysin O (ASO), and c-reactive protein (CRP) were detected. ResultsFor joint fluid-related indicators, TP and ALB levels were not significantly different between the two groups (P > 0.05), while WBC, GLU, UA, RF and ASO between the two groups were significantly different (P < 0.05); For blood indexes, C4 was not significantly different between the two groups (P > 0.05), but IgG, IgM, IgA, CRP, C3, UA, RF and ASO were significantly different between the two groups (P < 0.05). The detection rate of ASO from the joint fluid was significantly higher than that detected from the blood in both the two groups (P < 0.05), while UA level was not significantly different between the joint fluid and the blood (P > 0.05). In patients with rheumatoid arthritis, RF detection rate was not significantly different between the joint fluid and the blood (P > 0.05), but it was significantly different for patients with gouty arthritis (P < 0.05). The positive rate of ASO in the blood and joint fluid of patients with gouty arthritis was respectively 38.7% and 44.0%, and it was 75.0% and 73.5% for patients with rheumatoid arthritis. UA positive rate in the blood and joint fluid of patients with gouty arthritis was 92.0% and 80.0% respectively, while it was 38.2% and 32.4% for patients with rheumatoid arthritis. RF positive rate was 33.3% and 40.0% in the blood and joint fluid of patients with gouty arthritis, while the rate was 86.8% and 91.2% for patients with rheumatoid arthritis. ConclusionThe joint fluid and blood indicators are in change in patients with gouty arthritis and rheumatoid arthritis, which has a certain clinical value in disease diagnosis and curative effect observation.
